Modular Raspberry Pi Cluster Rack & Frame

Thank you to @Krapozok for coming up with a modular Raspberry Pi rack design.

I didn't want to buy the frame that these modules sit within, so printed them!

The frame is still 2U in height, and comes in 8 parts due to the print size restrictions of my Ender 3 Pro, although in hindsight I could have made it in 6. There's the left and right parts (2UFrL & 2UFrR which are actually the same), then top and bottom centre pieces 2UFrTC and 2UFrBC which are again the same.

The pieces bolt together using M4 bolts and nuts. I suggest 14-16mm in length.

Bolts:

The frame includes spacing holes for not just the v1 modules from Krapozok but also anything of half the size, allowing greater mounting options.

It's personal preference, however I suggest brass knurls be purchased (5mm OD, 3mm length, M3 thread) and are press inserted then heat sealed into the frame for module fixings.
